However, the presence of this bacterium in cheese is little known. On the other hand, quinolones are considered first-line drugs for the treatment of campylobacter infection in human patients, but currently little data is available on the levels of resistance to these antibiotics among <em>Arcobacter</em> species. Thus, the objective of this study was to analyze the susceptibility of <em>Arcobacter</em> spp. isolated from 100 fresh cheeses, obtained from the municipal markets to Fluoroquinolones in Guaranda City, Ecuador. By culture, 47 out of the 100 cheese samples were positive with a total of 66 isolates. By PCR, the number of positive samples was reduced to 21 with 26 isolates. With respect to antimicrobial activity, 2 isolates showed resistance to Levofloxacin (7.69%) and 6 to Ciprofloxacin (23.08%). Nineteen strains exhibited intermediate resistance to Levofloxacin and 10 to Ciprofloxacin. This study is the first report on the presence of pathogenic species of <em>Arcobacter</em> spp. in fresh cheeses in Ecuador, which could act as a vehicle for transmission to humans and pose a potential risk to public health. https://cjes.guilan.ac.ir/article_5584_43b5160f965916ef2f7f1be9a0fd38a6.pdf
